Technical size and spacing of the inflow

I have a Ford 5000 tractor radiator that I'm going to use in my '28-'29 grill shell to cool my 59AB flatty.

Can anyone tell me the size and spacing of the inflows from the water pumps at the top tanks of the radiator and the outflows at the bottom tank so I can bring said radiator to the shop and have the modifications done?

Thanks
